The range of test conditions on the dynamometer shall be sufficient to determine the primary operating characteristics corresponding to the full range of vehicle operations. The transmission characteristics to be determined for all driving ranges or gears are:

1. 1 Efficiency versus output speed.
2. 2 Torque ratio versus output speed.
3. 3 Input speed versus output speed.
4. 4 Output torque versus output speed.
5. 5 Parasitic losses versus input speed.
